Title: Improvements in or relating to cathode ray tube circuits for television receivers
Inventor: BERNARD GEOFFREY GEORGE
IPC: H04N3/20
Filed: 1948-06-09
Abstract: 649,738. Television receivers. SCOPHONYBAIRD, Ltd. June 9, 1948, No. 15553. [Class 40 (iii)] In order to prevent excessive brilliance of the presentation on the screen of the cathoderay tube 12 of a television receiver, a limiting device 18 is so connected in the grid-cathode circuit of the cathode-ray tube as to prevent the potential of the cathode of tube 12 with respect to that of the control grid falling below a predetermined positive value. The signals derived from the video amplifier 10 are applied via the circuit 13, 14 to the cathode of the tube 12, the grid of which is maintained at a constant adjustable potential by means of the tapping on the potentiometer 16 which is byepassed to earth by the condenser 19. The diode 18 prevents the potential at the anode of valve 10 from falling below the potential of the grid of tube 12, whereby, since a steady potential is produced across the resistor 13 owing to the current flowing in the cathoderay tube, the potential of the cathode is not allowed to fall below a predetermined positive value with respect to that of the grid.

Patent GB-144707-A (GB)
Title: Improvements in or relating to the welding of aluminium and aluminium alloys to metals such as iron or the like
IPC: B23K35/28
Filed: 1920-06-10
Abstract: 144,707. Metallindustrie Schiele & Bruchsaler. June 3, 1918, [Convention date]. Compound forms; sheets.-In a method of welding thin sheets or foils of aluminium or aluminium alloys, e.g. 0.005 to 0.100 mm. in thickness, to sheets cf iron or of other metals having a melting-point above that of aluminium, the surfaces of the foils and sheets are separately provided with an extremely fine roughening or matt before being placed together for welding. The consequent annealing of the iron which is necessary when ordinary aluminium sheets are welded to iron plates and then cold-rolled into sheets is thus avoided, and the melting or loosening of the aluminium prevented. The roughening may be produced by cold-rolling of the sheets and foils in separate packs. The iron sheets may also be roughened by brushes or by sand blasting, etching, &c. The sheets and foils are then separately annealed and are then placed together in an air-tight manner with roughened surfaces inwards. They are then heated to about 600‹ C. and welded by passing through rolls, the pressure being such as to stretch the foil as much as possible, but only to stretch the sheets slightly. The Specification as open to inspection under Sect. 91 (3) (a) states also that the composite sheets are subsequently heated to 500‹ C. to anneal the foil. This subject-matter does not appear in the Specification as accepted.

Title: Method for reclaiming used active carbon
IPC: C01B31/08
Filed: 1976-04-21
Abstract: 1494162 Reclamation of active carbon TAIYO KAKEN CO Ltd 21 April 1976 [21 April 1975] 16212/76 Heading C1A Used particles of active carbon are reclaimed by passing an electric current through the carbon particles so as to heat them, the electric current being passed through the carbon particles in a reclaiming zone manitained filled with the carbon particles and through which the particles progressively move in a direction generally parallel to the flow of electric current, and wherein a gas is blown through the carbon particles in a direction countercurrent to the direction of movement thereof, to remove gases desorbed from the surfaces of the particles in the reclaiming zone. The reclaiming zone is suitably a substantially vertical column through which the particles (which are preferably spherical) move with the aid of gravity; preferably the upper and lower ends of the zone are defined by a generally horizontal electrode plate having a plurality of openings therethrough of a size to permit the carbon particles to pass therethrough to enter or leave the reclaiming zone, the electric current being applied between the electrode plates. At least 25% of the surface area of the plate, desirably at least 40%, may be represented by said openings. The heat-treatment may be carried out in two stages, a pre-heating stage followed by a desorption stage. Where several kinds of materials having different desorption temperatures are adsorbed on the carbon particles, the contaminants may be separately desorbed and recovered by appropriately controlling the voltage applied to a plurality of pairs of electrode plates arranged to form several reclaiming zones in series.

Abstract: 240,909. Cachemaille, A. S., (Westing- house Lamp Co.). July 7, 1924. Vacuum tubes; R÷ntgen-ray tubes.-A thoriated metallic filament is heated in a reducing atmosphere prior to its insertion in a,bulb so as to produce an electron emissivity equal to that of metallic thorium. In the preferred process a - continuous length of thoriated tungsten filament is heated in an atmosphere containing the vapour of a hydrocarbon to a temperature high enough to produce reduction of thoria to metallic thorium. As shown the filament 2 is passed from a spool 3 through a chamber 4 to a spool 5. Nitrogen or an inert gas, mixed with a hydrocarbon, for instance by bubbling through benzene 6, is passed through the chamber. The filament is heated to a dull red heat by current from a battery 16 supplied through mercury cups 14, 15. It is suggested that some or all of the thoria is reduced to metallic thorium, or that tungsten carbide or thorium carbide is formed on the surface of the filament. A protective coating may be formed by passing the filament over a pulley dipping in a varnish such as a solution of nitro-cellulose or amyl acetate. The filament is mounted in the bulb and heated to drive off the coating, and a clean-up agent such as aluminium or magnesium may be contained in the bulb.

Abstract: 655,491. Switch contacts. REYROLLE & CO., Ltd., A., ALLAN, A., and SMALL, J. F. S. June 18, 1948, No. 16448. [Class 38(v)] In a self-aligning butt contact arrangement for a circuitbreaker, either the fixed or the moving contact comprises a contact member mechanically connected to its supporting member through a part spherical surface on one member engaging a part cylindrical surface on the other member to permit tilting and bodily movement of the contact member against spring action. In Fig. 1, the fixed contact comprises a fixed part B, a supporting member C, an inner housing D slit longitudinally to provide contact fingers, and the part spherical tilting member A which engages the contact fingers and is biassed towards the moving contact E by a spring G and thrust cap F. The cap F has a part spherical surface F<SP>1</SP> engaging a bore A<SP>1</SP> in the member A: When the contacts are closed, the moving contact E may move the tilting contact member A a short distance vertically in the housing D and the member A may tilt within the housing so as to bring its lower surface into correct alignment with the contact E. The outward movement of the member A under the bias of the spring is limited by the inturned flange C<SP>1</SP> of the support C, though in modifications, the extent of this movement may be determined by a screw or screws on the member A engaging in a slot or slots in the housing D (Fig. 2, not shown), by ball headed studs extending through springs G into recesses in the member A (Fig. 4, not shown), by slotted links Q, Q<SP>1</SP> connected between the members A, B, Fig. 6, or by securing the spring G to both members A, B (Fig. 7, not shown). In all these modifications and as shown in Fig. 6 the arrangement may be such that as the contacts separate the member A is tilted, so that the separation always occurs between the same points on the contact surfaces. Both contact members A, E may be provided with erosionresisting inserts A<SP>5</SP>, E<SP>1</SP> at these points, slots A<SP>3</SP>, E<SP>2</SP> being provided to confine the arc to these inserts. In Fig. 4 (not shown). the housing D is formed by hairpin-shaped fingers so that the electrodynamic forces set up by the current in the fingers tend to maintain the fingers in firm contact with the contact member A. The contact member A may be formed with a slot in a lateral plane to cause the current in the contact to flow in a loop which tends to blow out the arc in a transverse direction. Fig. 5 shows a modified arrangement in which the fixed member B is provided with a part spherical surface B<SP>1</SP> and the tilting contact member is formed by a cup N with an inner housing N<SP>1</SP> having fingers engaging the surface B'. A chain P limits the movement of the cup N.
